Abstract/OtherAbstract:

Muscle haematomas (MH) represent 10-25% of all bleeds in patients with severe haemophilia. We performed a cross-sectional survey on current practice in the management of MH with participation from 22 consultants. The respondents reported 492 MH/year, corresponding an average of 25/centre, mostly associated with trauma. Iliopsoas (55%), calf (18%) and thigh (18%) bleeds were scored as most serious. Half of the respondents distinguished between contusion and strains, whereas the majority (68.2%) did not categorize bleedings as intra- or intermuscular, although 77.3% routinely used ultrasound. Half of the respondents used a standard protocol for the management of MH. Twenty of 22 (90.9%) respondents offered physiotherapy in the hospital following MH, with no clear consensus on timing and type of treatment. In a theoretical case, for a 70-kg patient with a soleus triceps haematoma, the average initial dose of factor VIII was 2730 U (range: 1750-4000) twice daily for 3-5 days. In a similar case of a patient with inhibitors, 31.8% reported first-line and only use of either recombinant factor VIIa (rFVIIa) or activated prothrombin complex concentrate (APCC), while 36.4% switched between bypassing agents. Using rFVIIa, the median dose was 100 μg/kg (range: 85-270) and with APCC, the median dose was 70 U kg(-1) (range: 50-100). The majority (68.2%) did not use antifibrinolytics. Resolution of pain (81.8% & 77.3%) was regarded as the key clinical marker of arrest of bleeding as compared with diminished swelling and improved range of motion. The survey outlines limited consensus in the management of MH in patients with haemophilia and highlights potential topics for future studies.
